Abstract:
A preform is made by mixing cyclic olefin copolymer (COC) and light shielding pigment(s) with PET. The preform is stretch-blow moulded to produce a bottle which may be white and opaque. Light may be restricted from entering the bottle to thereby restrict degradation of the bottle contents from certain wavelengths of visible light.
